DEMOUNTABLE WHEEL;

Application led June 29, 1917. Serial No. 177,687.

To @ZZ whom it may concern.'

Be it known that l, VILLIAM N..BoofrH, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful improvements in Deiountable Wheels, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to vehicle wheels of the non-demountable type, and it is the object of the invention to provide means for converting such wheels into the deniountable type. To this end the invention comprises the novel construction of attachment and replacement elements and t-he method of assembling the same as hereinafter set' forth.

In the drawings: Figure l is a cross-section through anondemountable wheel; y

Figure 2 is a similar section showing the same converted into a demountable wheel;

Figure 3 is a side elevation partly in section of the construction shown in Figure F igure l is a view similar to. Figure 2 showing a forward wheel construction.

My invention is 'applicable to various types of non-demountable wheels, but as specifically shown is designed for use in con-r nection with the Ford wheel. As shown in Figure l, this wheel comprises .wooden spokes A, the hub B having an integral spoke-clamping fiange C on its inner side, and an annular flange D on its kouter side with clamping bolts E passing through said flanges and spokes and secured by nuts F. where the wheel is used for kthe rear or driving wheel a brake-drum G is secured to the hub by the same bolts Ei passing through apertures in the inwardly-extending flange H. y

My improvement for converting such a wheel to a demountable vtype comprises a bushing I having a cylindrical portion for sleeving over the hub andan outwardly-ex-v tending flange portion J for lying adjacent to the inner faces of the spokes. This flange is provided with a series of apertures L which register with the positions of the bolts E and are preferably of a polygonal form. M are a series of studs forming replacements for the bolts E and which are formed with threaded inner end porbearingagainst the outerfface of the hub y flange 1C, and outwardly-extending portions i3 for .passingfthroughthe spokes threaded at their outer ends for engaging clamping;`

nuts Q. There are also preferably provided bushings or thimbles R of a size to loosely nt aboutthe portions P of the studsl To convertfthe wheel as shown in Figure 1 intothe construction shown in Figure 2,

the wheel and huby are removed from theaxle and the hub is then detached by removing the bolts E. Thecentral openingvis" then enlarged by-cutting away ther spokes sufficiently to receive the bushing I, and the holes for the bolts E are also enlarged to receive the thimbles R which are inserted therein from the inner side of the spokes The bushingl is then placed upon the hub and the studs M are secured to the flange C by inserting theA threaded" portions N through the apertures iii-said flange and( lplacing thapolygonal portion 0 in the polygonal apertures L of the flange .Llnuts N.

being engaged with thethreaded portions N to clamp the studs'. The spoke portion of the wheel may then be engaged with the hub, inserting the ends of the studs M into ther thimbles R, which latter'are slightly flared at their inner ends, as indicated at R for receiving said studsfwhile thenuts N are slightly loosened to permit the studs to align themselves with said thimbles. annularclamping plate D is next placed in position and the nuts Q engaged with thev studs and tightened, afterfwhich the nuts N- The may be also tightened. To hold the latter nuts from disengagement lock washers S` are preferably vinserted between the saine and flange Cfand where the brake-drum G is secured to the wheeltheflangeI-I thereof is clamped by thesamefnuts N, as shown in Figure 2.k i, f

After Lthe parts are' assembled as just described, the wheellmay at any time be demountedwby merely 'rernoving the nuts tionfand engagingthe nuts @and tightening the same.

'lo secure'the member I from' accidental displacementy it is ypreferably attached 'to' the spokes by aplurality of wood screws T` passing through the flange J. Also this flange J isprovided with a series of apertures U- intermediate the apertures L, and which are adapted to register with apertures V in the flange C, as shown in Figures 3 and l. These apertures V in the normal construction of wheel are used for the passage of wood screws which secure the cyclometer gear in position, but with the converted construction I dispense with these wood screws and use in place thereof headed bolts IV. The heads of these bolts are on the outer side of the flange C and will engage with the apertures U in the flange J, while the inwardly-projecting threaded ends of the bolts may be used for securing the cyclometer gear.

The combination of the replacement element is simple and inexpensive, and t-he operation of converting the wheel is also one which can be quickly performed. The thimbles R protect the wood of the spokes from the abrasive action of the screws in repeated mountings and demountings and thus prevent injury to the wheel. y

What I claim as my invention is:

l. The combination with the hub of a vev hicle wheel ofthe non-demountable type,

4v'said hub havin(T a Spoke-clam ainO' flan 'e C .s D e and .a detachable spoke-clamping flange adapted to be bolted thereto, of a series of `replacement studs having threaded inner yand outer ends, the former engaging the bolt apertures in the hub flange and provided with a shoulder for abutting against said flange, nuts for clamping said studs to said'flange, nuts for engaging the outer ends' ofthe studs and clamping the detachable flange to the spokes, a bushing for the wheel adapted to sleeve upon the hub, and means on said bushing engaging said studs to lock the same from rotation. 1

2. The combination with the hub of a vehicle wheel of the non-demountable type, said hub having a spoke flange, ka spoke section and a detachable clamping flange, of means for securing the spokes to said spoke flange including a series of replacement 'studs having shouldered bearings forengaging said spoke flange and adapted to be secured thereto, means adjacent to said spoke flange engaging said studs for locking the `same from rotation, and thimbles for i 'engaging apertures through the spokes in alignment with said studs and loosely .fitting the latter. i

3'. The combinationwith the hub of a vehicle. wheel of the non-'demountable type, said hub havingan integral spoke-clamping flange, aspoke4 section and a demountable clamping flange, of a bushing for engaging the spoke section having an outwardly` extending flanger on' the inner sides of the spokes, replacement studs having shouldered bearings for engaging the integral spoke clamping flange and portions non-revolubly engaging apertures in the. bushing flange, nuts forr clamping the inner ends ofsaid studs to the integral spoke clamping flange, and nuts for engaging the outer ends of said studs to clamp said demountable clamping flange.

e. The combination with the hub of a vehicle wheel of the non-demountable type, said hub having an apertured spoke ange, a spoke section and a detachable clamping flange, ofv a bushing engaging Vsaid spoke section and adapted to sleeve over said hub, a flange extending outward from said bush-- ing and provided with polygonal apertures therein, replacement studs having polygonal shouldered portions for engaging' the polygonal apertures, inwardly extending portions for engaging' the apertures in said spoke flange and outwardly extending portions, said studs having inner and outer threaded portions, and nuts Jfor engaging the inner and outer threaded portions of said studs.

5. The combination with the hub of a vehicle wheel of the non-demountable type, said hub having an integral apertured spoke clamping flange, a spoke section and4 adevtachable clamping flange, of a bushing for engaging the .spoke section and adapted to sleeve over said hub, a flange extendingoutward from said bushing lying adjacent to said integral apertured spoke )clamping flange and provided with polygonal apertures for registration with the apertures 1in said integral spoke clamping flange,
